Just remove those 2 and carefully test all outputs for any differences. This is where i want to see if there is a change. Where are you with this? Those are gone |

Ok, we have to be getting close. There is not much left. Remove R429 and R434 and retest all.

One more thing I noticed just now rechecking if the new FL was - or +, as the power is on longer and I re test those points the voltage there goes down. I went to FL first this time and it was .7 so I left the Probe there and it slowly went down to the .333.
Not sure if that means anything.

Really needs to be zero. Here is what is left on that FL. Once these are removed there is nothing connected to it.
Remove C404 and retest. After that it is only R411.
If the FL goes to zero now but you still have some on the other channels try removing Q403, Q405, R407 and C403.

ok FL is now -.200 where it stabilizes. the rest are the same.
R411 is coming out now.
But i just wanted to see something. I pulled the Protection cable and re measured all the voltages. they all went up to 2.xx but FL went down to - .08.
Re connected the Protection cable and all went down a volt but FL stayed at - .08
Hmmmmmmmmmm
